• Do not use this heater for heating human living quarters.
• Use of direct-fired heaters in the construction environment can result in exposure to levels of CO, CO2, and NO2 con-
sidered to be hazardous to health and potentially life threatening.
• Do not use in unventilated areas.
• Know the signs of CO and CO2 poisoning.
• Headaches, stinging eyes
• Dizziness, disorientation
• Difficulty breathing, feels of being suffocated
• Proper ventilation air exchange (OSHA 29 CFR 1926.57) to support combustion and maintain acceptable air quality shall
be provided in accordance with OSHA 29 CFR Part 1926.154, ANSI A10.10 Safety Requirements for Temporary and Por-
table Space Heating Devices and Equipment used in the Construction Industry or the Natural Gas and Propane Installa-
tion Codes CSA B149.1.

the shift and after 4 hours.
• Provide ventilation air exchange, either natural or mechanical, as required to maintain acceptable indoor air quality.
